In this draft version of the conclusion to his Nobel speech, Marshall Nirenberg explores the relationship between genetic and neurological subjects that foreshadow his professional transition in the coming years. He suggests the genetic code probably evolved earlier than neural codes and was frozen at a relatively early date because "soon after a sufficient amount of information had been selected and stored in nucleic acids, alternatives of the code probably were limited to those that would not radically alter the retrieval of information that had been requested."
